Re: Stus-List Yanmar cutting out at sea?

[Paul Fountain via CnC-List]

I’d also pull the fuel pick tube and see if there is a screen in the end of it, 
if there is one remove it - it’s likely picking up sediment and starving the 
engine, dropping ir when the engine stops.

If it that or the filters I would either polish the fuel, and add a cleaner, or 
remove it and have the tank cleaned.

Just brought my new-to-me C home. My 2009 Yanmar 3YM30 purred like a kitten 
in most seas. But this was a 30 hour slog through hell. Decided to motor-sail a 
bit in some heavy seas (20-25 kts), engine, at 2500-2800 rpm, would suddenly 
lose revs then often quit. Could start up again in a few moments, but would do 
it again in 5 minutes or so. Gave up on it until winds died down and started it 
up no problem... worked flawlessly for a 2 hour motor in calm waters after 
that. Boat was fully serviced in fall and on hard until 2 weeks ago when I 
bought and launched it. Has a Racor filter/water separator and inline fuel 
filter. I'm wondering if the exhaust being under water during that point of 
sail would cause the issue or maybe I should just change up filters, or was it 
probably sediment in tank being kicked up and starving the engine? Thoughts?

I suspect muck at the bottom of your fuel tank is getting stirred up when 
you’re bouncing around and that’s clogging either the intake or filter. Have 
you looked at your fuel filter recently?

Re: Stus-List garboard drain install for a 30-1

[WILLIAM WALKER via CnC-List]

Nate,   I did this last fall.  Best thing I have ever done for the boat.   I 
used rare earth magnets as you suggest.  Taped one inside bilge where I wanted 
drain and other magnet "pops" into place on outside.  I drew a circle around 
the outside magnet and drilled from the outside.    Make sure wherever you 
locate the drain that it has clearance to install the plug from inside if like 
mine.      I sealed the edge of hole with epoxy before installing the thru 
hole.    I used all bronze Perko.  More expensive.  Some of the cheaper ones 
have brass plugs, not bronze, with bronze thru hull.    For winter, I hung a 
length of cotton clothes line with a nail stuck through it in the middle to 
keep from falling out the hole to wick the last bit of water out of bilge.  
Worked great.   Good luck.

I plan to install a garboard drain in my 1980 30-1 for this winter. Port leaks 
and only a partial cover meant significant  water/ice in the bilge last winter, 
which did some damage.
Any comments or suggestions? My default is to use rare earth magnets to line up 
bilge position and outside, drill from inside, install bronze seadog drain with 
epoxy and screws. 
Thanks
